Definition of onchocerciasis

Answer 1

Onchocerciasis, also known as river blindness, is a disease caused by the parasitic worm Onchocerca volvulus. It is transmitted to humans through the bite of infected blackflies of the genus Simulium. The primary symptom of onchocerciasis is severe itching, which can be debilitating. In addition, the disease can lead to skin conditions and vision impairment, and in severe cases, it can result in blindness. Onchocerciasis is primarily found in certain regions of Africa, parts of Latin America, and the Arabian Peninsula. Treatment typically involves the use of ivermectin, which helps to manage symptoms and prevent transmission of the disease.
